After piling up the defeated monsters
Rodan, Anguirus and King Caesar, Godzilla uses his
atomic ray to finish off the trio, killing them
in a bath of flames.

Background

Originally drafted, Godzilla was supposed to
kill everyone of his opponents through the
course of the film. In context, it does seem
odd that Godzilla would seemingly spare his
three foes, settling for what would appear
to be just their defeat.

One possibility for this cut is for consideration
of two of Toho's most recognizable characters:
Rodan and Anguirus. It's not out of the question
given history, as producer Shogo
Tomiyama previously barred the use of
Anguirus in Kamoebas' role Godzilla:
Tokyo S.O.S. (2003). However, according
to reports, the sequence not being included
and completed has more to do with not wanting
to destroy the suits for such a scene, so
they could later see promotional use.

Note: Another image was
overlayed on this particular picture and Godzilla's
hand and arm, from another shot, appear in
the lower left corner. Furthermore, Godzilla's
beam charging in the exaggerated manner was
also added in via photo manipulation.
